Something else.
Yummy. I cubed mine and made it into kabobs with Japanese eggplant and zucchini. I also tried the marinade on beef and it is equally delicious.
Used different ingredients.
This is an excellent recipe, though I made a few adjustments. First, I marinated the fish (salmon and mahi mahi) overnight instead of for just one hour. Second I added a tablespoon of ginger and chilli paste for a touch more complexity. Both fish were wonderful, I will be sure to use this again and again.
DELICIOUS! I used 1/2" thick "spot" fillets for this recipe. (spot is what they are called locally here in southeastern North Carolina, silver with a black spot and yellow markings; I don't know if they have other names elsewhere). I was afraid the difference in thickness would make the marinade too strong, but since I had about a pound of fillets, I decided to chance it. They were perfect, grilled in about 3 minutes on my indoor grill. YUMMY! Will be using this recipe again and again. My picky children wouldn't touch it though.
